Servo drive stepless ISD integrated
Stepless is the technology invented and developed by CMZ for low speed applications.
Through the closed loop control, a stepper synchronous motor can be controlled with modulated current by:
eliminating any problem due to the step loss
reducing the motor temperature.
Compared to the brushless solution, on the same motor size the Stepless technology provides higher torque at low speed. This makes it most suitable for a wide variety of low speed applications.
ISD is our stepless integrated servo drive for decentralized architecture, featuring:
- internal programmability
- CANOpen, PROFIBUS, MODBUS RTU protocols
- usability with all master controllers using CODESYS.
It is available in 3 different models from 4,6 Nm to 12 Nm.
